commander of the USS Greeneville, the submarine that crashed into a Japanese fishing vessel as it emerged in waters off Hawaii, took sole responsibility for the fatal February exercise that claimed the lives of nine Japanese. A group of U.S. civilians were onboard the Greeneville as part of a distinguished visitors program designed to promote public support for the U.S. Navy. Waddle acknowledged that mistakes had been made and corners had been cut aboard the 6,900-ton nuclear sub but said his actions were not criminal. He received a reprimand in April and retired from duty.
